Solar Cell

Solar Cell or Solar Cell is a device or component that can convert sunlight energy into electrical energy using the principle of Photovoltaic effects. What is meant by Photovoltaic Effects is a phenomenon in which the appearance of an electric voltage is due to the connection or contact of two electrodes connected to a solid or liquid system when obtaining light energy. Therefore, Solar Cells or Solar Cells are often referred to as Photovoltaic Cells (PV). This photovoltaic effect was discovered by Henri Becquerel in 1839.

Electric current arises because of the energy of the photons of sunlight that it receives successfully freeing electrons in N-type and P-type semiconductor connections to flow. Just like Photo Diodes (Photodiode), Solar Cells or Solar Cells also have Positive legs and Negative feet that are connected to a circuit or device that requires a power source.

Basically, the Solar Cell is a Photo Diode (Photodiode) which has a very large surface. The wide surface of the Solar Cell makes this Solar Cell device more sensitive to the incoming light and produces stronger Voltage and Current than Photo Diodes in general. For example, a solar cell made of silicon semiconductor material is capable of producing voltages as high as 0.5V and currents as high as 0.1A when exposed to sunlight.
